Question juridique clé
Whether the federal appeal had to be declared inadmissible because the advance on costs was not paid within the prescribed time.
Solution extraite
Yes. The appellant neither paid the required advance nor submitted proof of payment, nor withdrew the appeal; inadmissibility followed under the summary procedure.
Motifs extraits
After the court ordered a CHF 2,000 advance under Art. 62(1) LTF and set an additional non-extendable deadline under Art. 62(3) LTF, the appellant remained inactive. Under Art. 108(1)(a) LTF, the appeal could therefore be dealt with summarily and declared inadmissible.
